Entity annotations

Our corpus contains annotated typed entity references. We annotate text strings as entity references when they refer to clearly distinguishable individual instances in the real or fictional world. This makes entity references highly related to mentions from coreference resolution, although there are some conceptual differences. We further annotated the type of the referred entity as part of the entity reference. In determining the type of the referred entity, we handle fictional worlds in the same way as the real world. In the absence of other indications, we assume that fictional worlds follow the same rules as the real world.

The types we distinguish are

Person: Reference to humans or humanly acting animals or things

Organisation: Reference to an organisation

Location: Reference to a place or location

Work: Reference to a cultural artefact (publication, law)

Event: Reference to an event

Concept: Reference to domain-specific theoretical concept
